VbzCart/tables/ctg groups

About

• Purpose: Master list of Supplier Catalog Management Groups (SCMGs) -- see VbzCart/pieces/catalog/building
• Fields:
  • ID_Supplier: supplier to which this group applies; NULL = no fixed supplier, can be used for any of them
  • ID_Redir: ctg_groups.ID -- if not null, redirect all references to the current ID to use ID_Redir instead. This is used to indicate a disused SCMG (at the moment, I can't remember why it was better to do this than to just edit the existing SCMG, but I'm sure there was a reason).
• Future: It may be that ID_Redir isn't really a useful thing to have. For now (2010-11-17), I'm not going to bother making it editable in the administration form.
